I was told a story about a time capsule in Covina, CA, USA same result nothing found, because hermetic sealing wasn't figured out until a year after that one was buried. This clearly shows the capsule was breached and 200 years of water, air or moisture will ruin anything organic. Worst case it was human ashes, I doubt something like that, Kosciuszko died in Switzerland, but it would be interesting to do some mineral x-ray gun atomic analysis on the remainders to see paper? cloth? only silt?. The Westinghouse one was done about as well as you can preserve organic things like paper and cloth. Also reminds me of the TMBG song "By the time you get this" https://www.youtube.com/watch?v=XsCOajqLycI https://www.youtube.com/watch?v=XsCOajqLycI
